How NCS Works

The Network Control System (NCS) provides summary displays of resource types, and graphic displays of individual resources and their subordinate nodes.

NCS functions by issuing VTAM Display commands and interpreting the responses received.

Transfer of NCS Data Across an INMC Link

NCS also collaborates with other, linked CA NetMaster NM for SNA regions, by using the Inter-Management Services Connection (INMC) facility. VTAM Display commands can be executed on other CA NetMaster NM for SNA regions in other VTAM domains for processing, and responses can be returned to the original NCS for display, as shown in the following illustration.

Note: This can occur only if the user has access to the other NCS, and the user IDs in both regions are the same.

This illustration shows how VTAM Display commands can be executed on other CA NetMaster Network Management for SNA regions in other VTAM domains for processing, and responses can be returned to the original NCS for display.

In the previous illustration, note the following:

Arrows indicate the flow of data.
NCS in domain A sends VTAM display command requests to NCS in domain B, which returns responses. These responses can be displayed by NCS A.
